To all whom t may concern Be it known that I, ALBERT E. BnALL, a citizen of the United States, residing at Clinton, county of Clinton, and State of iowa, have invented new and useful Improvements in Drainage Systems, of which the following is a specilication.

In some parts of the country 'water is held in the soilnear the surface because it cannot escape through the underlying layer of clay-or similar moisture repelling material. lf it happens that a gravel layer or stratum underlies the clay wlthin a reasonable distance, it is possible to bore down through the clay into the gravel land thereby drain oli' the water which would other- .wise be distributed through the soil near the surface. To do this in an elticient manner under ordinary Working conditions, it

is necessary to keep the bored hole from collapsing or lling up and special precautions must be taken to keep the passage Open so that in all seasons and under all .conditions there may be a ready exit of the surface Water into the lower 'gravel 'or porous stratum.

certainty that v.when in place, the structure will provide for leading H the Water to the underlying stratum 'without danger that vthe passage will become clogged or that the structure will become broken or displaced throu h changes in weather or accidental distur ences from above. v

l,Wit-h these and other objects in view, the

, structure is composed in large part of ordinary porous t there being only three additional members necessary Ato build up the structure as a whole. All the parts are floor or bottom ofthe chamber 1 0. This-is suitably anchored together and the construction 1s suchthat the tile will not sink into the ground orl be displaced even in case it must handle large quantities of water and furthermore it provides means for allowing 55 the water to pi ipitate its suspended matter before entering thedrain, thereby eliminating in large measure the danger of clogging the passage.

The invention Will be better understood from the detail Adescription of the accompanying drawings in which- Figure l is an elevation of an embodiment of the invention indicating y,somewhat diugrammat-ically its position in the soil. F ig. 2 is a perspective detail of the large covering disk. F ig. 3 is a perspective detail. of the crown which serves to support the disk. Fig. ehshows the 'tubular member used to support the crown. Fig. 5 shows the 70 platform whereby the structure as a whole K I receives support from the soil, and Fig. 6 shows the topmost of the tile members forming the continuous depending tube of the structure. 75

When using the present invention, a hole is dugto form a Water receiving chamber 10 which may be several feet in diameter and sunk to-a depth 'belowthe frost line. This chamber is to serve as a reservoir or settling tank for the water seeping in from the surrounding soil preparatory to withdrawal of that water through the drain. Near the center of this chamber l0 is sunk an opening or well deep enough to strike the gravel or `other porous stratum through Which-the water can be drained off. Into --this Well a series of ordinary tile sections l1 are lowered these being placed one on top of the other and preferably fastened together by support. wires l2 which serve as slings whereby the tile may be lowered into the gravel. After this tube is in position, there is tted to its upper end a heavy disk 13 recessed at 14 to receive the upper tile section and strong enough to serve as a supporting platform to which the tile may be secured by the Wires l2 and by which the entire column of tile may receive support from the ftion of the parts within'chamber 10 and so interrupt the passage through which the water must be `conveyed away, The upper tace oi" this" circular disk or platform 13 is' provided with an annular groove 15 to rey ceive and anchor the lower end ofthe tubular member 16. This tubular member 16 is preferably nothing more than an ordinary tile of a diameter somewhat larger than tile', lt may vtherefore be purchased inthe? 11. open market and need not be specifilly pronotched at 19 to lit pver and: rest on the upper edge of tile 16. These lugs are spaced far enough apa-rt to permit-the passage of water over the top edge of tile 1'6. lrt-cover f vided or shipped to the tarmer.- Surmounting this tile section 16 is a crown 17 o circular outline having depending vlugs 18 1 20 which may be in the form of a disk, and A relatively heavy, rests onl and is supported by'crown 17 and serves as a roof for chamber 1i) and also by its weight holds the parts i 17, 16 and 13 in lirlir engagement with one another.

By Amaking the cover somewhat concave or V(lished, .lateral displacement is prevented and additional security 1s lnsured. i

After the parts have been assembled as over the disk 20 to a depth of two or three:

feetand the soil above may be tilled from y year to year without any disturbance to the up the entire structure' merely bythe drainage system beneath and without dan-cL ger of a cave-in under normal conditions.

nary porous tile and theplatform 13 andi crown 17 and cover 20'may be of concrete or other strong and rigid material and when? shipped 'to the user will allow himto build tion ot the necessary tile 11 and 16. NVhen water seeps through into chamber over into the outlet until the level of water addi.

has risen to the upper edge of tile 16. l'nother words, there is a retardation in c hami ber 10 giving ample opportunity for sedi-- ment-to settle within that chamber so that' water delivered over tile 16 is in large measurelpuriied and in condition4 'to 'run ol' freely through thegravel stratuifr vltorfj anvreason 1t should, `bebo1ne desirable to open up chamber 10\ for removal of thel collected sediment, this may be done very readily without disturbing the column of tile y 11 it being only/,necessary to dig down to the'cover 'Q0 andlift it out ltolgether with the crown 17 and the tube 16 whereupon the en- Y tirechamber 10 can be cleaned out without injany.way' disturbing the supporting plat- LClamS.

Y Having thus described vform 13 and the column of tile suspended therefrom.

While 1 have herein shown and described only one embodiment of my invention, it is to be understood that various'changes and modiicationsmay be made by those skilled in the art without departing from the scope ot myinvention as deiined in the appended my invention what I claim as new and desire to secure by Letters Patent is:
